Feature/improve game ux

[silkirep13]

Hello!

I came across this project and really liked the concept. I decided to implement a few changes to improve the overall User Experience (UX) and clean up the code slightly.

Changes implemented:

1. Fixed Typos: Corrected spelling errors (e.g., "Unknow" -> "Unknown", "know actions" -> "known actions").
2. Input Handling: Added .strip().lower() to the input method. Now the game accepts commands even if the user accidentally adds spaces or uses uppercase letters (e.g., "Walk " or "WALK").
3. New Feature ('points'): Instead of printing the score after every single move (which can clutter the screen), I added a specific command points. The user can now check their score on demand.
4. Better Onboarding: Added a welcome message at the start of the game displaying all available moves, so the player knows what to type immediately.

How to test:
Run the script and try typing points to see the current score after doing an action.

I hope you find these changes useful!
